A surgical instrument is disclosed herein. The surgical instrument can include an end effector comprising a first jaw and a second jaw, a plurality of electrodes positioned within the jaws of the end effector, a flexible circuit comprising a conductive track configured for multiplexed transmission of a plurality of signals to and from the end effector, a control circuit communicably coupled to the plurality of electrodes via the flexible conductor, and a memory configured to store an algorithm configured to cause the control circuit to: receive signals from the plurality of electrodes; determine an impedance based on the signals received from the plurality of electrodes; detect a media positioned between the jaws of the end effector based on the impedance; determine a position of the detected media along the longitudinal axis based on the received signals; and generate an alert associated with the detected media and the determined position.

Devices, systems, and methods for detecting tissue and foreign objects during a surgical operation

A surgical instrument including a signal interference detection system.

Surgical instrument comprising a signal interference resolution system

A staple cartridge comprising a power management circuit is disclosed.

Staple cartridge comprising a power management circuit

A method for sensing tissue data and managing processing power is disclosed.

Method of powering and communicating with a staple cartridge

Disclosed is a surgical end effector for use with a surgical instrument. The surgical end effector comprises a jaw, and a staple cartridge seatable in the jaw. The staple cartridge comprises a sensor array configured to take measurements corresponding to a parameter associated with a function of the surgical instrument, a processor, and a memory storing program instructions. The memory storing program instructions that, when executed by the processor, cause the processor to perform an initial calibration of the sensor array, determine an initial adjustment to the measurements based on the initial calibration, perform an in-use calibration of the sensor array, and modify the initial adjustment based on the in-use calibration.

Monitoring of manufacturing life-cycle

A staple cartridge comprising a cartridge body, a sensor array, and a thermal control system is disclosed.

Staple cartridge comprising a sensing array and a temperature control system

Disclosed is a surgical instrument, comprising: an end effector configured to grasp tissue. The end effector comprises a jaw, and a staple cartridge seatable in the jaws, wherein the staple cartridge comprises a sensor array. The surgical instrument further comprises a power source configured to supply power to the staple cartridge, and a transmission system configured to wirelessly transmit at least one of the power and a data signal between the staple cartridge and the surgical instrument, and a control circuit. The control circuit is configured to detect a bandwidth of data transmission through the transmission system, detect a discharge rate of the power source, and select a sensor sampling rate of the sensor array based on a detected value of the bandwidth and a detected value of the bandwidth and a detected value of the discharge rate.

Adjustable communication based on available bandwidth and power capacity

A surgical system comprising a stapling instrument and a staple cartridge including a plurality of independent circuits powered by the surgical instrument is disclosed.

Surgical instrument system comprising a power transfer coil

A surgical system may include tiered-access features. The surgical system may be used to analyze at least a portion of a surgical field. Based on a control parameter, the system may scale up or down various capabilities, such as visualization processing, endocutter communication, endocutter algorithm updates, smart cartridge connectivity, smart motor control for circular stapler, smart energy control, cloud analytics, hub connectivity control, and/or hub visualization and control interactions. The control parameter may include system aspects such as processing capability or bandwidth for example and/or the identification of an appropriate service tier.

Method for operating tiered operation modes in a surgical system

A surgical instrument is disclosed herein. The surgical instrument can include an end effector that includes jaws configured to transition between an opened condition and a closed condition, a plurality of electrodes positioned within the jaws of the end effector, a control circuit, and a memory configured to store an algorithm configured to cause the control circuit to determine an impedance signal based on signals received from the plurality of electrodes, detect a media positioned between the jaws of the end effector based on the determined impedance signal, determine a position of the detected media based on the received signals, and generate an alert associated with the detected media and the determined position.

A method for establishing signal and power communication between a surgical instrument and a staple cartridge is disclosed.

A staple cartridge is disclosed, for use with a surgical instrument, having a cartridge body including a proximal end, a distal end, and staple cavities, staples removably stored in said staple cavities, a sled movable toward said distal end during a staple firing stroke to eject said staples from said staple cavities, a sensor configured to detect the position of said sled; a cartridge control circuit in communication with said sensor; and at least one memory device in communication with said cartridge control circuit, wherein said cartridge control circuit is configured to store data in said at least one memory device regarding operation of the staple cartridge.

Staple cartridge comprising an information access control system

Disclosed is a surgical instrument, comprising an end effector configured to grasp tissue. The end effector comprises a jaw, and a staple cartridge seatable in the jaw, wherein the staple cartridge comprises a sensor array. The surgical instrument further comprises a power source configured to supply power to the staple cartridge, and a transmission system. The transmission system is configured to wirelessly transmit the power from the surgical instrument to the staple cartridge, monitor an efficiency of a transfer of the power from the surgical instrument to the staple cartridge, and adjust a transfer parameter based on the efficiency of the transfer.

Adjustment to transfer parameters to improve available power

A surgical instrument controls communication capabilities between the surgical instrument and a removeable component. The surgical instrument may determine parameters associated with the surgical instrument and the removable component. Based on the parameters, the surgical instrument determines a level or tier of communication between the surgical instrument and the removable component. The surgical instrument may determine to configure one or more of the following levels: one-way static communication with the component; two-way communication with the component; real-time two-way communication with the component; and communication with a surgical hub.
